对两种贾汪镜煤质及其氢化产品经液体色谱分离得到的各段分进行了红外光谱鉴别,对芳烃段分还进行了紫外光谱考察.镜煤质、氢化油和石油醚可溶分的红外光谱基本相似,表明它们的基本碳骨架结构特征近似.两种镜煤质氢化产品相应段分的红外及紫外光谱图都很相似,表明它们含有非常近似的组分.按本文结果并结合前二报的结果推测,饱和烃段分主要由脂环(包括缩合脂环)化合物组成;芳烃段分主要由氢化芳香族化合物组成,其中单苯核芳烃主要为四氢萘系化合物,双苯核芳烃主要由萘系化合物组成.随着馏分沸点的增高与芳核数的降低,芳核上的氢被取代得越多,主要是被并合的脂环和甲基所取代,长链取代基和开链—CH_2—都不多.这些结果与图解统计分析的结果相一致.
Two kinds of jiawang mirror coal quality and its hydrogenated products by liquid chromatography separation of the various sections were identified by infrared spectroscopy of the aromatic section also conducted UV spectroscopy.Mirror coal, hydrogenated oil and petroleum ether soluble infrared The spectra are similar, indicating that their basic carbon skeleton structural features are similar. The IR and UV spectra of the corresponding fractions of the two mircohydrogenated products are similar, indicating that they contain very similar components. According to the results and combined with the first two According to the results of the report, the saturated hydrocarbon fraction mainly consists of alicyclic (including condensed alicyclic) compounds. The aromatic fraction mainly consists of hydrogenated aromatic compounds, of which the aromatic mononuclear compounds are mainly tetrahydronaphthalene compounds, Mainly composed of naphthalene compounds.With the increase of the boiling point of the boiling point and the reduction of the number of aromatic nuclei, aromatic nuclei are replaced by more hydrogen, mainly by the combination of alicyclic and methyl substitution, long chain substituents and No more open-chain -CH_2 - These results are consistent with the graphical statistical analysis.
